@Fasgadh @Richard_Littler Unconscious exposure is still exposure, and as they say, there is no such thing as bad publicity (within reason).
Unless you're previously committed to not patronising a particular company for principled, political, philosophical, or religious reasons. But then, it depends on exactly how strongly you feel. And you could still be swayed, even then. The marketers just need to work harder to convince you, is all.
"I'll NEVER buy anything from Amazon!"
Well, fair enough, but by definition, that means that Amazon is always prominent in your mind. If they continue to do the things that made you detest them, you will continue to be adamant in your decision. But if they start doing things which make you think, "Hey, they might actually be turning around," they could still win you back. Or if all of your friends start telling you how awesome they are, maybe you start gaslighting yourself into thinking they can't actually be that bad. Or you really really want a product and the only place to get it is on Amazon....
And even if not, if you're truly so hell-bent on Amazon, you're going to tell all your friends how terrible and evil they are and how you're never going to buy from them. But that puts them top of your *friends'* minds, which makes them more likely to buy from Amazon, if they don't feel quite so strongly as you do.
It's all deeply rooted in psychology and human nature.
